Green Iguanas (Iguana iguana) in mixed-species exhibits

“…Order Testudines.-Of the numerous examples of Green Iguanas exhibited with chelonians (Lonsdale and Klocek 1987;Sodaro 1999), the most commonly co-housed species is the Red-footed Tortoise (Chelonoidis carbonarius); examples include zoological institutions in Nebraska, Kansas, West Virginia, Florida, Texas, and Michigan, USA (Farmerie et al 1999;Sodaro 1999;Grazian 2012), Hong Kong, Singapore, England, Wales, France, Belgium, and Germany (Schwibbe and Ziegler 2002), as well as a live exhibit in a Florida museum. Green Iguanas also are frequently held with Yellow-footed Tortoises (C. denticulatus), with examples in two zoological institutions in Florida, USA, as well as Taiwan, England, and Maryland, USA.…”

“…A number of freshwater turtle species have been used to inhabit the aquatic sections of terraria and walk-through enclosures that display Green Iguanas (Lonsdale and Klocek 1987). Likely the most frequently co-housed turtles are sliders (Trachemys spp.…”

“…Box turtles (Terrapene spp.) also have been co-housed with Green Iguanas in zoological institutions in Florida and Illinois, USA (Lonsdale and Klocek 1987) and England.…”

“…In all these cases, the iguanas were adults. Small crocodilians such as Cuvier's Dwarf Caiman (Paleosuchus palpebrosus) have been co-housed with Green Iguanas in Illinois, USA (Lonsdale and Klocek 1987), Singapore, and The Netherlands, and the Smoothfronted Caiman (P. trigonatus) has been co-housed with Green Iguanas in Germany (Schwibbe and Ziegler 2002). The potential for iguanas sustaining injuries from dwarf caimans is probably mitigated by the animals being similar in size, as well as platforms and trees providing refugia inaccessible to caimans.…”

“…Order Cypriniformes.-Carp (family Cyprinidae), especially Koi (Cyprinus rubrofuscus), frequently inhabit ponds in enclosures displaying Green Iguanas and other animals (Lonsdale and Klocek 1987).…”
